The rotation of the cylindrical body 9 adjusts the position of the four openings 10 on the surface, so that the lamp tube 12 emits light with different brightness from different openings 10. When the light is adjusted, the handle 20 is loosened, the circular plate 18 moves outward under the rebounding force of the spring 19, the circular plate 18 moves outward to drive the circular rod 17 to move outward, and the outer end of the circular rod 17 is clamped into the circular hole 15, so that the circular ring 14 is conveniently limited, and the adjusted light brightness is conveniently limited. Thus, it is convenient to adjust the brightness of the light according to the shape of the exhibits, and the exhibits are conveniently displayed perfectly. Thus, the golden yellow light powder-free light source for exhibition is conveniently dimmed quickly, and many backup lamps do not need to be stored, thereby reducing the use cost of the exhibition cabinet dimming system.
